While driving, with out warning, the car felt like we hit some thing. A very Sudden Slam, the engine light came on. The Car did not stall. We did not lose control. Just a sudden quick bang. We then pulled over, shut the car off. Turned it back on. The light stayed on, no other light came on, and it runs like a charm. Was able to make it home with out further problems. The Car has felt like it has slipped while driving before. Any one have this problem?

The "check engine" light is an indicator for a system that monitors many electronic functions in the system, also called the "malfunction indicator lamp" (MIL). It can come on for any of hundreds of different causes from any of the systems that the computer monitors. Some are very important and can lead to further component or engine damage and some are emissions related not as serious but still a problem and need to be repaired.

Your first step is to have the computer scanned to retrieve the trouble codes that were set when the check engine light came on. Those codes will give you specific information about what the computer saw and will get you pointed in the right direction to find your problem. With a 1996 or newer and some 95 cars and you have an AutoZone or Advanced auto parts in your area, they will read them for free. Once you have these code numbers, we can be a lot more specific about what your problem may be.
